python json转字典编码_Python json转字典字符方法实例解析

josn基本操作

1.导入import json

2.字典转json：json.dumps(dict,ensure_ascii=False)，加,ensure_ascii=False转换之后无中文乱码

3.json转字典：json.loads(str)

4.json转字典：requests.get().josn()

5.返回字符串： requests.get().text

举例源码

#!/usr/bin/python3

# encoding:utf-8

import json

import requests

class jsonC():

def __init__(self):

self.url = 'http://wthrcdn.etouch.cn/weather_mini?city=北京'

self.geturl = requests.get(self.url)

#字典转json,因为python没json类型所以str表示

def dict_json(self):

d = {"name":"张三","age":18}

j = json.dumps(d,ensure_ascii=False)

print('dict_json函数：类型：',type(d),'转类型',type(j),'\n',j)

#json转字典

def json_dict(self):

s = '{"name":"张三","age":18}'

d = json.loads(s)

print('json_dict函数：类型：',type(s),'转类型',type(d))

#接口调用直接返回 字典(dict)

def get_json(self):

d = self.geturl.json()

print('get_json函数类型：',type(d))

#接口调用直接返回字符串

def get_str(self):

s = self.geturl.text

print('get_str函数返回类型：',type(s))

if __name__=="__main__":

js = jsonC()

js.dict_json()

js.json_dict()

js.get_json()

js.get_str()

运行结果

dict_json函数：类型： 转类型

{"name": "张三", "age": 18}

json_dict函数：类型： 转类型

get_json函数类型：

get_str函数返回类型：

调用get例子

返回json值：
